Laser hair removal is a medical procedure in which the diode laser, which generates intense pulsating beam of specific wavelength, removes unwanted hair. During the treatment, the energy of the laser is used to prevent regrowth of hair. To this end, the laser energy must penetrate a few millimeters into the skin to reach the hair root.
Although laser hair removal effectively removes hair, number of treatments depends on the psychosomatic and physiological factors that determine how many treatments are necessary for the desired result. The effectiveness of treatment depends on the color and thickness of hair, as well as the depth of their roots, so it takes more treatments in case of red and blonde hair compared to black hairs.
It usually takes several treatments of permanent laser hair removal, in order for the treated area to remain hairless for a longer period of time. Regular maintenance treatments might also be needed. The most commonly laser-treated are legs, armpits, upper lip, chin, bikini area, arms and intimate zone. However, unwanted hair can be removed from almost every part of the body, except the eyelids and the eyeball area.
It is important to undergo a treatment for several times in an interval of 4 to 8 months, since hair growth in humans in certain stages of the melanin containing hair basis is connected with the root of hair only in the stage of growth. Different types always find themselves in this stage at different times.
